I encountered this issue too. I needed it resolved ASAP for my work so I created a loop patch that partially implements the suggestion solution by overriding the create_datagram_endpoint method. Perhaps this might be of some use to the eventual ticket resolver. It can be found in the following gist: https://gist.github.com/claws/d4076b4b155695844d54 If this looks like it's progressing in the right direction I can try to implement it properly in `base_events.py` and submit it via a patch.
